Just a little advice to confirm what I think

J

The first set of photos are from GLOW and the second are from PreMom. Glow says my peak was CD 13 my OPK lines are as dark as each other. The second set says CD 13 is high but not peak then the OPK on CD 14 says it is peak. So which is right because they both positive. Thus one app is putting my O date later than the other. What do y’all think?
